ServersCheck Monitoring Software through 14.3.3 has Persistent and Reflected XSS via the sensors.html status parameter, sensors.html type parameter, sensors.html device parameter, report.html location parameter, group_delete.html group parameter, report_save.html query parameter, sensors.html location parameter, or group_delete.html group parameter.
ServersCheck Monitoring Software through 14.3.3 allows local users to cause a denial of service (menu functionality loss) by creating an LNK file that points to a second LNK file, if this second LNK file is associated with a Start menu. Ultimately, this behavior comes from a Directory Traversal bug (via the sensor_details.html id parameter) that allows creating empty files in arbitrary directories.
ServersCheck Monitoring Software before 14.2.3 is prone to a cross-site scripting vulnerability as user supplied-data is not validated/sanitized when passed in the settings_SMS_ALERT_TYPE parameter, and JavaScript can be executed on settings-save.html (the Settings - SMS Alerts page).
